Has anyone had these optional mechanical filters fitted to their 8600 Mk2?
What is the audio improvement on SSB and/or AM? (don't suppose anyone would have a video of two 8600 Mk2's side-by-side, one with and one without the filters fitted)
Can they be fitted by the user (carefully) or is it a solder job by a competent person?
